Even better: he faked his entire carreer AND he's doing everything completely on purpose!

I'd say I'm more afraid he's also a talented enterpeneur for a product of his speeches and personality. I've met some people called visionaires, and I'm sure he may be one of these. They are not necessary bad in their field, but their word is taken for granted in too many indisciplinary cases and they are succesful at selling it at many conferences worldwide. He may be a really talented economist, or a man that just have an instinct to getting a career here, it doesn't matter. That characteristics just makes him more likely to succeed at elections, winning the public.

More important to my judgement of him is that he uses a populistic platform of redoing everything from the ground up in an instance. I get people got fed up with previous governments, but nothing good happens overnight. It's a big red flag. Even if he's trully the savanth scientist who planned it all himself for 20 years and get it all perfectly right, the amount of changes themselves would cause a crisis. And him accepting it, not seeing it or serving some lobby makes him not a president material equally.
